Researchers use one-of-a-kind expertise and capabilities to test fuels of tomorrow
At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

Experimental results are presented which verify the possibility, formerly predicted,1 of the formation of a closed, spheromak-like magnetic configuration (SLMC) in a plasma focus discharge. The model is based on the self-generated transformation of a toroidal (i.e. azimuthal) field into a poloidal one. At its final stage, the SLMC takes the form of a squeezed spheromak, which includes a combined Z-v-pinch at its major axis, exhibiting a power density several orders of magnitude larger than that measured experimentally on a force-free flux-conserver-confined spheromak formed by helicity injection. The results suggest a possibility of further concentrating the plasma power density by means of compressing the SLMC-trapped plasma by the residual magnetic field.
